How do you test for the presence of iodine?

Testing for Iodide, I-

Sodium iodide, NaI, is the source of iodide anion for this experiment.

Reaction with bleach involves three steps. The brown color shows the presence of I3- ions.

Hypochlorite ion yields chlorine:

OCl- (aq) + Cl- (aq) + H2O

Cl2 (aq) + 2 OH-

Chlorine reacts with iodide anion:

Cl2 (aq) + 2 I- (aq)

I2 (aq) + 2 Cl- (aq)

Triiodide ion is formed:

I2 (aq) + I- (aq) I3- (aq)

Starch reacts with iodine and iodide to form a characteristic blue/black complex. A corn starch packing peanut is shown here.

Silver ion reacts with iodide to form silver iodide, AgI.

Ag+ (aq) + I- (aq) AgI (s)

Reaction of iodide with sulfuric acid produces hydrogen sulfide gas and brown triiodide solution in a series of reactions:

I- (aq) + H2SO4 (aq) HI (aq) + HSO4- (aq)

8 HI + H2SO4 (aq) H2S (g) + 4 I2 (aq) + 4 H2O

I2 (aq) + I- (aq) I3- (aq)

Again, starch is used to confirm the presence of iodine and iodide.

How accurate is a nine panle drug test?

A nine panel drug test may or may not be very accurate. The accuracy is directly related to the quality of the lab and/or sample for testing. "Nine Panel" refers to how many drugs(panels) the test is checking for. It seems to me that urine tests are less accurate than hair tests and hair tests less than blood tests. All three can show false positives, but only two can be tricked.

What can cause bloating after eating pain in left side of lower abdomen hiccuping and burping results of blood test showed liver not working properly?

In my experience what you are describing sounds like a possible gallbladder attack. I have stones and I experience bloating, burping, and pain in the left upper area of my abdomen , just under my ribs, if I eat anything with too much fat in it. The liver test could also allude to this, as the gallbladder and liver work closely together.
